here is a workaround of the posted link wich work with kubrik css.
replace this in your default css kubrik css
h1, h1 a, h1 a:hover, h1 a:visited, .description {
text-decoration: none;
color: #fff;
display:block;
height:100%;
text-indent:-600em;
}
and change the padding top
h1 {
padding-top: 0px;
margin: 0;
}
thats it! the image is now klickable and the text is here but not visibla because of the text indent.
(rename your new headerimage to kubrikheaderimage.jpg and
you can replace the standard image in wp-content/themes/default/images/kubrikheader.jpg)
check the directorie names by yourself maybe i have a failure in the spelling.
good luck!
